Abstract:
A composition and a solution for temporary bonding are provided. The composition includes a dianhydride monomer, a light-absorbing monomer, and a light-absorbing material. The light-absorbing monomer includes at least one of N,N,N,N-(p-aminophenyl)-p-phenylenediamine (DPDA) and N,N-(p-aminophenyl)-p-phenylenediamine (TPDA). The light-absorbing material includes carbon black and silicon dioxide.
Abstract:
A method of transferring micro devices is provided. A carrier substrate having a first surface and a second surface opposite to each other is provided, wherein a plurality of micro devices is disposed on the first surface, and each micro device binds to the first surface through laser debonding gel. Next, a receiving substrate is subjected to be relatively closer to the first surface, and a mask is provided on the second surface. Afterwards, the second surface with the mask is irradiated with a laser light, so as to keep the micro devices without laser irradiation binding on the first surface, and the micro devices irradiated with the laser light lose adhesive force and transfer to the receiving substrate.
Abstract:
A polyimide is provided. The polyimide includes a repeating unit represented by formula 1. In formula 1, Ar is a tetravalent residue obtainable from a tetracarboxylic dianhydride containing a fluorine-containing aromatic group or an oxygen-containing aromatic group, and A is
